Ancient Siberia was home to previously unknown humans, say scientists

Presentation Citation formats L. Arnold R. Roberts R. Macphee Willerslev, Eske A. Tikhonov F. We present chronological constraints on a suite of permanently frozen fluvial deposits which contain ancient DNA aDNA from the Taimyr Peninsula of north-central Siberia. The luminescence phenomenology of these samples is first discussed, focusing on the optically stimulated luminescence OSL decay curve characteristics, thermoluminescence TL properties, and signal compositions of quartz from these previously unstudied deposits.

Geographic Russian Siberia. Siberia has been part of modern Russia since the latter half of the 16th century. The territory of Siberia extends eastwards from the Ural Mountains to the watershed between the Pacific and Arctic drainage basins. The river Yenisey conditionally divides Siberia into two parts, Western and Eastern.

Numerous settlements found between N and N across Siberia, dating from about 32, to 24, cal BP are evidenced by the presence of the MUP.

CNN Scientists studying the remarkably well-preserved remains of an Ice Age bird have identified the specimen as a horned lark. Chat with us in Facebook Messenger. Find out what’s happening in the world as it unfolds. The 46,year-old specimen was identified as a horned lark. Radiocarbon dating revealed the bird lived around 46, years ago, and genetic analysis identified it as a horned lark Eremophila alpestris , according to a paper published Friday in the journal Communications Biology.

The bird was found in north-eastern Siberia at a site which also contained other frozen specimens. Read More. The preservation of the bird is explained in large part by the cold of the permafrost, explained Dussex, but this specimen is in extraordinarily good condition. Is it a dog or is it a wolf? Scientists working in the area have also found carcasses and body parts from other animals such as wolves, mammoths and wooly rhinos.

Dussex described such findings as “priceless” as they allow researchers to retrieve DNA and sometimes RNA, a nucleic acid present in all living cells. Using carbon dating on the creature’s rib bone, experts were able to confirm that the specimen had been frozen for around 18, years, but extensive DNA tests have so far been unable to show whether the animal was a dog or a wolf.

First parrot fossil unearthed in Siberia

MOSCOW: Researchers have unearthed the first parrot fossil in Siberia, dating back 16 to 18 million years, the furthest north these birds have ever been found. Updated : 3 years ago. The discovery of a single parrot bone in the Baikal region suggests that the birds, which today mainly inhabit tropical and sub-tropical regions, may once have been widespread in Eurasia.

Oldest Connection with Native Americans Identified Near Lake Baikal in Siberia

Using human population genetics, ancient pathogen genomics and isotope analysis, a team of researchers assessed the population history of the Lake Baikal region, finding the deepest connection to date between the peoples of Siberia and the Americas. The current study, published in the journal Cell , also demonstrates human mobility, and hence connectivity, across Eurasia during the Early Bronze Age. Modern humans have lived near Lake Baikal since the Upper Paleolithic, and have left behind a rich archaeological record.

Ancient genomes from the region have revealed multiple genetic turnovers and admixture events, indicating that the transition from the Neolithic to the Bronze Age was facilitated by human mobility and complex cultural interactions. The nature and timing of these interactions, however, remains largely unknown. A new study published in the journal Cell reports the findings of 19 newly sequenced ancient human genomes from the region of Lake Baikal, including one of the oldest reported from that region.

The main surface outcrop of the volcanic rocks predominantly basaltic lavas and tuffs are found on the Siberian Craton east and south of the thick-dashed line on the map, right , and on the Taimyr Peninsula. However, extensive subcrops of basalt also occur beneath the West Siberian Basin or Siberian Platform Surkov, , beneath the Yenesei-Khatanga Trough, and beneath the Kara Sea; the total area and volume of these ‘hidden’ basalts may exceed those of the main outcrops to the east.

Sporadic outcrops of Permo-Triassic basalt occur in the Urals and in the Kuznetsk Basin, and our recent dating studies have shown that many of these are contemporaneous with the Permo-Triassic boundary Reichow et al. Intrusive rocks occur throughout the region, especially on the Siberian Craton around the main outcrops of lavas, and basaltic pyroclastic rocks are abundant in the lower parts of the volcanic succession Fedorenko et al. On the craton, the basalts erupted onto, or intruded into, Palaeozoic sedimentary sequences, including the coal-bearing Permo-Carboniferous Tunguska sequences.

In the West Siberian Basin, the basalts lie on top of Palaeozoic or Proterozoic basement, although the precise nature of this contact is poorly constrained from borehole and seismic data. The Siberian Craton is old, cold and thick, unlike the much younger lithosphere of the WSB, which is young, thin and hot. Furthermore, whereas the Craton has remained stable since the Permian and probably for a long time before that , the Palaeozoic surface of the West Siberian Basin has subsided.

Not only has this resulted in deep burial of the basaltic sequences, but it has helped create substantial oil and gas fields – some of the world’s largest Peterson and Clarke, Deep, north-south trending rifts occur within the WSB. Now buried beneath several kilometres of sediment, these structures contain thick sequences of Permo-Triassic basalt see review by Saunders et al. The relative timing between rifting and volcanism remains unconstrained.

Oxford University scientists have played a key role in new research identifying the earliest evidence of some of the first known humans — Denisovans and Neanderthals, in Southern Siberia. Professor Tom Higham and his team at the Oxford Radiocarbon Accelerator Unit at the University of Oxford worked in collaboration with a multi-disciplinary team from the UK, Russia, Australia, Canada and Germany, on the detailed investigation over the course of five years, to date the archaeological site of Denisova cave.

Situated in the foothills of Siberia’s Altai Mountains, it is the only site in the world known to have been occupied by both archaic human groups hominins at various times. The two new studies published in Nature , now put a timeline on when Neanderthals and their enigmatic cousins, the Denisovans, were present at the site and the environmental conditions they faced before going extinct.

Official websites use. Share sensitive information only on official, secure websites. By: Steven M. A suite of new accelerator-mass spectrometer AMS radiocarbon ages provides the first reliable chronology for late Quaternary sediments in Lake Baikal. In this large, highly oligotrophic lake, biogenic and authigenic carbonate are absent, and plant macrofossils are extremely rare. Total organic carbon is therefore the primary material available for dating.

Several problems are associated with the TOC ages. One is the mixture of carbon sources in TOC, not all of which are syndepositional in age. This problem manifests itself in apparent ages for the sediment surface that are greater than zero. The other major problem with dating Lake Baikal sediments is the very low carbon contents of glacial-age deposits, which makes them extremely susceptible to contamination with modern carbon.

This problem can be minimized by careful sampling and handling procedures. The ages show almost an order of magnitude difference in sediment-accumulation rates among different sedimentary environments in Lake Baikal, from about 0. The new AMS ages clearly indicate that the dramatic increase in diatom productivity in the lake, as evidenced by increases in biogenic silica and organic carbon, began about 13 ka, in contrast to previous estimates of 7 ka for the age of this transition.

The problem of absolute dating of Siberia’s Quaternary geomorphological complexes

This paper presents new data related to the emplacement ages of the Amakinskaya and Taezhnaya kimberlites of the Mirny field, Siberia, located in the southern part of the Yakutian diamondiferous province. This study analyzed rutile and titanite grains along with zircons for U-Pb isotope composition by laser ablation LA -inductively coupled plasma-mass spectrometry ICP-MS and evaluated the applicability of rutile and titanite for the dating of kimberlite emplacements.

Both minerals contain substantial admixtures of common Pb in their Pb isotope composition. Therefore, the Pb method was applied for common Pb correction during age calculation. All age estimates correspond to the main epoch of diamondiferous kimberlite activity in the Siberian platform and suggest the formation of the Mirny kimberlite field within a single event or two separate events occurring close together in time.

The majority of these ornaments are decorated in the Scythian animal style. This paper aims to present the large variety of distinct processes used in the manufacture of these gold artefacts. The technical expertise and the equipment at the disposal of the Early Iron Age craftsmen can be inferred from tool marks and analysis of surface structures. The early date of these finds, demonstrated by a combination of radiocarbon and dendrochronology, supports the assumption that this particular, sophisticated style of early Scythian metal work originated in the Tuva region.

Arzhan, in the district of Turan, is located in a plain where hundreds of kurgans are arranged in alignments. The wooden chamber of the burial no. During the excavations of , more than gold items were discovered in the undisturbed royal burial no. The results of current research on Arzhan 2 are forthcoming Chugunov et al. They were adorned with personal ornaments, such as torcs, necklaces, ear ornaments, pendants and pins. In addition to gold beads, beads of different materials, such as carnelian, garnet, glass paste, malachite, and turquoise, are also present in the ensemble of personal ornaments.
